ATENT EDWARD WESTON, CF NEWARK, NEW JERSEY, ASSIGNOB TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF NEW YORK, N. Y. I

lNCANDE SCENT-LAMP HOLDER.

SPECIFICATION forming part of Letters Patent No. 274,427, dated March 20, 1883.

' Application filed July 19, 1882. (NomodeL) To all whom it may concern:

Be it known that I, EDWARD WEs'roN, a subject of the Queen of Great Britain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Incandescent-Lamp Holders, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

My invention consists in a device for bolding an incandescent lamp, the said device being constructed and arranged in substantially the following manner; to an insulating-base of any suitable description I attach two metal rods with hooks on their ends. Thesero'ds, wires, or pins extend up from the base nearly parallel with each other, and should be about an inch or more in length. pass a comparatively stout spiral spring, the diameter of the spiral bein g such that there is no danger of contact with the rodswithin it. The spiral rises somewhat above the ends of the rods or wires on the base when it is in its normal condition, or not compressed.

The lamp to be used with this holder is any one of the ordinary incandescent lamps, the only change from the usual construction necessitated being to bend the wires at or near the points at which they pass through the glass into eyes. If the spiral spring be com pressed,

the hooked ends of the rods rising from the base be inserted in these eyes, and the spring allowed again to rise, the lamp will be held firmly in place by the upward pressure of the spring. To complete the circuit through the lamp the hooked rods are connected with the line-wires of a circuit.

The appended drawingsillustrate the abovedescribed construction in detail.

Figure l is a view in elevation of the holder and lamp connected; Fig. 2, avertical section of the insulating-base, showing. the hooked rods connected thereto. Fig. 3 is a detached view of one of the rods, and Fig. 4 a view of the same bent into the shape of a hook.

For convenience, I use a base, B, of wood or hard rubber, shaped somewhat like an ordinary bolt, with a screw-threaded shank, by means of which it may be connected to an ordinary bracket. The central portion of the base (designated by the letter C) is slightly higher than the rest; or a groove is cut into a flat surface, the purpose of such configuration Around them I .base-to the conductors of the lamp, and a being to hold in place a spiral wire or spring, D. The base B is perforated at two points, and pins E E, which should be screw-threaded, passed through and secured in the same. The pins E are bent into hooks at the upper ends, as shown, and have screws 6 e in their heads, or similar means of connecting to them the circuit-wires. The wires F F of the lamp A, at or near the points where they pass through the glass, are bent into books or rings f f or these rings or eyes may be formed in the wires in any other way.

It is evident that when the lamp is in place vertical or lateral movement, under any ordinary conditions, is effectually prevented by the action of the spring, while the latter is held securely in position by the raised portion of the base.

It may be stated that the shape of the lamp and the character of the base are matters that do not affect the invention, which comprehends such combinations of devices as will hold an incandescent-lamp globe to its base by connections made to its conductors, and hold it at the same time in proper position by the compression of a spring that tends to force the lamp away from the base.

"What I therefore claim is- 1. The combination of a base or support and an incandescent lamp, connections from the 8 spring acting to force the lamp away from the 5 base, whereby it is held in position, substan; tially as hereinbefore set forth.

2. The combination of a base or support and an incandescent lamp, wire connections between the conductors of the lamp and the base, and a spiral spring surrounding the connecting-wires, and arranged to force the lamp away from the base, whereby it is held in position, as set forth. 7

3. The combination, with a base or support and hooked rods or wires secured thereto, of an incandescentlamp having conducting-wires provided with rings or eyes, and a coiled or spiral spring placed upon the base, and arranged to exert a pressure upon the lamp when in position, as described.

In testimony whereof I have hereunto set my hand this 18th day of July, 1882.
